Bitcoin hardware wallet manufacturer Foundation has secured $6.4 million in new funding, led by Fulgur Ventures with participation from Arche Capital and other investors, as it pushes beyond self‑custody into broader digital security use cases. The round brings the company’s total funding to $16.5 million, though the valuation and round structure were not disclosed.
Alongside the raise, Foundation announced the general availability of Passport Prime, its flagship device that combines a Bitcoin hardware wallet with FIDO security key functionality, 2FA code storage, a password vault, and 50 GB of encrypted storage. Priced at $299 (regionally listed at approximately $354), the device is marketed as the first “Human Authority Hardware™” designed to require explicit human approval for every sensitive action.
Passport Prime runs on KeyOS, a microkernel operating system written in Rust with apps sandboxed for isolation. It also features QuantumLink, an encrypted Bluetooth subsystem on a separate chip that enables wireless connectivity without exposing secrets.
The company plans to launch a KeyOS app store by the end of Q2, opening the platform to third‑party developers. Cake Wallet has been named the first external team building on KeyOS, with further integrations expected throughout 2026 spanning Bitcoin, identity, and AI agent authorization. The strategy reflects a wider industry trend of transforming single‑purpose wallets into comprehensive authorization hubs for an increasingly automated digital life.
